Fybogel Sachets contain ispaghula husk, a natural soluble fibre that works as a bulk-forming laxative to help relieve constipation and maintain regular bowel movements. When mixed with water, ispaghula husk absorbs liquid in the intestines, swelling to form a soft, gel-like mass that makes stools easier to pass. Fybogel can also be used to help manage bowel function in conditions such as irritable bowel syndrome (IBS) or after certain bowel surgeries. It is usually taken once or twice daily, with plenty of fluid, to ensure effectiveness and reduce the risk of blockage. This gentle, non-habit-forming remedy is suitable for adults and children over 6 years.
Fybogel contains the active substance Ispaghula Husk. It is an easy and convenient way to increase the fibre in your diet helping your digestive system work more efficiently and gently relieving constipation the natural way. As it works naturally with your body, it takes care of constipation without undue straining, discomfort or unnatural urgency, helping to restore and maintain regularity.
Fybogel can be used whenever increased fibre is needed in your diet to relieve constipation; including constipation during pregnancy. It can also be used to help maintain normal bowel function if you suffer from haemorrhoids (piles).

Fybogel (Ispaghula Husk) Sachets may be used during pregnancy and if you are breast-feeding.
You should not take more Fybogel (Ispaghula Husk) Sachets than you should. However, if you do take more than directed, drink plenty of water.
If you forget to take Fybogel (Ispaghula Husk) Sachets and a dose is missed, do not take a double dose; just carry on with the next recommended dose.
Fybogel is a bulk-forming laxative. It contains soluble fibre (ispaghula husk), which absorbs water in the gut to increase stool bulk. This helps regulate bowel movements naturally. It is not a stimulant laxative and does not act as a stool softener in the same way as medicines like docusate.
Fybogel may help people with diverticular disease (the long-term condition, not an acute flare-up) by increasing fibre intake and maintaining regular bowel movements. However, it should not be used during acute diverticulitis attacks when the bowel is inflamed. You should always follow your doctor’s advice if you have diverticular disease.
Both products contain ispaghula husk as the active ingredient. The difference is mainly in the flavouring and sweeteners used. Fybogel Hi-Fibre Orange is formulated with added sweeteners and flavour to make it taste more palatable, but the laxative effect is the same.
Yes. Because ispaghula husk absorbs excess fluid in the intestines, it can help firm up loose stools as well as soften hard stools. This makes it useful in both constipation and mild diarrhoea.
Fybogel doesn’t force the bowel to move, but it helps regulate stool consistency and stimulate natural movement. This may mean more regular and predictable bowel movements, but it does not usually cause excessive or urgent trips to the toilet.
Not exactly. Fybogel works by bulking and softening stools, which helps the bowel move more efficiently. It does not directly speed up digestion of food, but it may improve overall bowel regularity.
You can take Fybogel at any time of day, but many people prefer taking it after meals. It should not be taken immediately before bedtime, as lying down straight after can increase the risk of choking or blockage.
Fybogel (ispaghula husk) and Laxido (macrogol) are both laxatives but work differently. Fybogel is fibre-based and works gradually, while Laxido is an osmotic laxative that draws water into the bowel to soften stools more strongly. Which is more effective depends on the type and severity of constipation. Your doctor or pharmacist can advise which is most suitable for you.
Lactulose is an osmotic laxative that softens stools by drawing water into the bowel. Fybogel is a bulk-forming fibre laxative that regulates stool consistency. Both are effective, but Fybogel may be gentler and more natural for long-term use, while lactulose may be better if stools are very hard. Suitability depends on your individual situation.
Yes, Fybogel is generally considered safe for people with kidney conditions, as it is not absorbed into the bloodstream and works locally in the gut. However, if you are on a fluid restriction or have been told to avoid high-fibre supplements, consult your doctor before use.
Fybogel may reduce absorption of other medicines if taken at the same time. It should be taken at least 30 minutes before or after other medicines. Always check with your doctor or pharmacist, especially if you take medicines for the thyroid, heart, diabetes, or epilepsy.
Fybogel can help manage some symptoms of irritable bowel syndrome (IBS), particularly constipation or alternating bowel habits, by regulating stool consistency. However, not everyone with IBS benefits from extra fibre, and in some cases it may worsen bloating or gas. It’s best to introduce fibre gradually and discuss with your doctor.
Yes, Fybogel can usually be taken with omeprazole. To avoid reduced absorption of your medication, make sure to take Fybogel at least 30 minutes before or after your omeprazole dose.

Fybogel (Ispaghula Husk) is a bulk-forming laxative containing soluble fibre from psyllium seeds. When mixed with water, the husk absorbs liquid and swells to form a gel-like mass that increases stool bulk and water content. This stimulates natural peristalsis (intestinal contractions) and promotes regular bowel movements.
The increased fibre also helps normalize stool consistency – softening hard stools while firming loose ones. Effects typically occur within 12-24 hours but may take 2-3 days for full benefit. It’s important to drink plenty of water to prevent intestinal blockage.
